ipplcation filed April 252.

I@ all i12/wm it may concern Be it known that l, Rnnonr W. Bean, tir.,:L subject of the Emperor of llermany, residinget Buffalo, in the countyof llrie and State of New York, have invented certain new and usefulImprovements in l'iose Couplings, of which the following is a speentication.

My invention relates to improvements in hose couplings, and moreparticularly' to quick acting hose coupling such as is employed forcoupling the ends of consecutive lengths ot fire hose. i

The Object of my invention is to provide a simple and effective couplingwhereby the ends of adjoining lengths ot hose may he quickly united ordisconnected without the necessity of turning the respective lengths of.hose relatively'.

A further object is the provision of at coupling of this type having fewparts und which requires only the proper relative placement of one )artwith respect to enother and the actuation of a single locking element.

The invention consists in the novel i'eatures of construction :ind inthe arrangement and combination of parts to be hereinafter described andparticularly pointed out in the subjoined claims.

In the drawings-Figure l is an elevation. of a hose showing twoadjoining lengths coupled together hy means of my improved coupling'.Fig. 2 is :i longitudinal sect' through the coupling and the adjacentends of two adjoining hose lengths. Fig. is a longitudinal sectionthrough the coupling showing the two main members disconnected. Fig. iis a transverse section taken on line 4 4, Fig. Fig. 5 is :i sectiontaken on line 55, Fig. Fig. 6 is a detached perspective viei' of thelocking member.

Reference being had to the drawings in detail, the reference numeral 7designates two adjoining hose lengths coupled together by means of myimproved coupling S.

The coupling comprises two mein members 9, l0, which are preferably inthe iorni of tubes or hollow cylinders, one of which is counterhor'ed,:is at l1E to receive the ndjzicent end of the other, thus theseniemhers are in the form of male und female parts, one fitting partlyinto the other. iy counterboring the member' 9, an internal shoulder 12is provided, against which is ,seated a gasket lf3, und the inner end ofSpecication of Letters Patent,

member il) is adapted to be forcibly pressed :against said-gasket so asto make a watertight joint between the two members. The mule member hasan external annular flange .Il between its ends which, as shown, isstepped, and itting around said unile member is a locking member l5 inthe form of a ring, the opening of said locking member being doublecounterbored to correspond to the stepped l'lzinge il on the melemember. The i'iange il enters saidv counterbored Iopening` so as toprovide a plurality ot' smooth bearing surfaces which tend to minimizethe tendency ot' the purts wearing, due to one turning upon the otherand this construction also renders the parts free in action.

rlhe female member has elongated lugs or extensions i6 at dizunetricellyopposite points, each of said extensions having a lougitudinal bore 1TJformed therein. lidably retained in said bores are yielding lockingpins or studs i8. llach ot' the hores li' is enlarged et opposite endsto provide oppositely-facing shoulders 19, 2U. Arranged in one ot' seidenlarged portions and surround` ing' the pin or stud 18 is a. coiledspring 2l which bears with one end against the shoulder l5) and with itsother end lageinst a nut 22 threaded onto the pin or stud 1S, said nutbeing coniined within the bore and made adjustable on the pin or stud soas to regulate 'the tension of the sprinfr. Against the other shoulderi() is adapted to hear a collar or ilange 'i3 formed on the pin 18. Thiscollar limits'the morement ol.t said pininrone direction7 such movementbeing caused by the pension ot' spiral spring '21 surrounding the pin.The opposite pins are placed under euual tension so that they will actin unison` und exert equal pressure in coupling the members ot' thecouplingtogetherf Said ionizing' pins project beyond the outer end l'areoi the female member il and are provided with enlargements or heads 2lat their proiectiiigends.

"ihe locking member or ring 15 is provided with segmental slots 25, eachslot heing enlarged :it one end, as at 26, the enlargements heing of asize to permit the heads 24 of the pins 18 to be passed therethrough.The outer face of the locking member is provided at opposite sides ofthe sluts with inclined or Wedgesshaped portions 2T which ride under andin Contact with the heads of the pins when 'turning the locking member.This movement of the .heads l ot' the locking pins.

locking member causes compression ol the springs l bv reason otl thelocking pinslbeing moved outwardly.y such movement being continued untilthe pins` reach the opposite endsI et' the slots` at which pointsthehighest elevation otI the inclined or wedge-shaped portions T arereached. and directly bevond deln'essions '3S are formed to receive theWhen the heads are seated in the depressions. accidental unrmlpling olvthe parts cannot talee place, since the springs 'il arc placed undersul'lieient tension to prevent outward movement oi the locking pinsAmllicientlv to, cause the heads thereof to ride onto the wedgeshaped orinclined portions 2i' without suflicient manual cli'ort being exerted tocause such action. rThe outer c vlindrieal ends of the main members havethe hose sections 7 secured thereto b v means of clips or other suitablemeans.

In order to couple two lengths of a hose together, it is simplynecessary to insert the male member l0v partlyvv into the female memberuntil the stepped flange of the male mei'nbci' closely approaches orbears against; thi'i'outer, face ot' the female member. The lockingrring 15 is then positioned to enter the locking pins in these-ginentalslots and asthe collars or flanges 223 ot" said pins holdthe latterprojected a certain distance so that theheads of the .same arepositioned toiride upon the inclined er erigir-shaped portions of saidslots, it is only necessaryY to rotate they locking ring.` whereupon themembers'l and l0 are pressed firmlyl into position7 they being retainedby the locking pins which are held properly Seated against Jthe ringbysaid springs. Reverse action of the parts in onliy necessary in order todiscenneet the hose len gths.`
